Concoct + Potential consuming 2-3x flask and power charges when used with crossbows

If you slot support gems like concoct or potential into crossbow skills that use ammunition, simply switching from another ammunition or reloading will trigger the effect. E.g., I'm experimenting with the unique armor that has a 20% chance to grant power charges on hit and slotted concoct and potential into fragmentation rounds for increased bleed magnitude and crit chance. Firing the rounds consumes both flask charges and a power charge and reloading consumes them again, effectively costing 2x what it should. If switching from another skill like permafrost bolts, you're consuming 3x what it should, as the game counts switching skills as a "reload." Both of these effects happen with the individually slotted support gems as well.
